Various 1,4‐diols are easily accessible from alkenes through iron‐catalyzed aerobic hydration. The reaction system consists of a user‐friendly iron phthalocyanine complex, sodium borohydride, and molecular oxygen. Furthermore, the effect of additional ligands on the iron complex was examined for a model reaction. The second hydroxy group is installed by direct C(sp3)H oxygenation, which is based on
通过铁催化的需氧水合很容易从烯烃中获得各种1,4-二醇。该反应系统由用户友好的酞菁铁络合物,硼氢化钠和分子氧组成。此外,针对模型反应检查了其他配体对铁络合物的影响。第二个羟基是通过直接C(sp 3)H氧合而安装的,这是基于烯烃的正式水合形成的瞬态烷氧基的[1,5]氢转移过程。
